Linedef type 177

Linedef type 177, Crumbling, No Respawn, Floating, Bobbing, is a type of floor over floor platform which will sink several units when jumped or stepped upon by a player, then crumble and fall. Once it crumbles, it will float on the surface of a water block positioned below it. If jumped or stepped upon while in the water, it will bob up and down briefly. Unlike linedef type 176, this platform will not respawn at its original location after landing on the water.

Setup

The flats, floor height, and ceiling height of the FOF are determined by the flats, floor height, and ceiling height of the control sector, and the sidedefs of the FOF's walls are determined by the sidedef of the controlling linedef.

The light level of the control sector will determine the brightness of the shadow cast by the FOF. If the light level of the control sector is lower than that of the target sector, then it will cast a dark shadow. If the light level of the control sector is higher than that of the target sector, then the FOF will illuminate the area below it. If the light level of the control sector is equal to that of the target sector, then the FOF will not affect the light of the area below it.

If this FOF is not placed over a sector with a water block positioned below it, it will still sink a few fracunits and make the crumbling noise, but it will not fall. If the Not Climbable flag is used, the player will be required to spindash to make the FOF move if it has not fallen yet; however, the FOF will still crumble even if the player does not spindash when standing on top of it.
